Something to be understood about the Feds stepping in...
In general, the trend for federal to state funding has been to cut funding to individual states for education, highways, etc. This is why many colleges have pushed tuition costs to students over the past couple decades because of a massive drop in federal funding to state universities.
MMJ has been such a tax boon for the states that have legalized that the financial incentive is in their favor to CONTINUE not to follow federal regulation.
2016 - Colorado pulled in 200 million in tax revenue from MMJ. You think the state government would calmly let the feds take that from them? Doubtful.
Even if the feds decided to crackdown on MMJ tomorrow, they would likely get no cooperation from the states and the entire process would be prolonged, perhaps indefinitely. It would be a lose-lose battle of state v fed.
Not saying the feds couldn't bring the hammer down and destroy an industry, but the resources to do so would be met with such a backlash that I don't think it would be possible, particularly when such things need to pass through the Legislative Branch.
